Dr. Bernstein was the FIRST person in the WORLD to get the Vbeam Perfecta® laser and helped with its development. It is a premiere pulsed-dye laser (PDL) for treating vascular lesions such as facial redness and rosacea, and is a go-to device for facial rejuvenation of sun-damaged skin. In addition to removing unwanted redness, one of the 5 key signs of skin aging, it also causes inflammation that remodels damaged collagen and elastic fibers improving fine lines and wrinkles. Dr. Bernstein and his collaborators have published extensively in the peer-reviewed literature on various uses of this versatile device.
